In 1972, a JV between Westinghouse and Newport News was formed called Offshore Power Systems. They aimed to mass-manufacture large floating PWR nuclear plants in a gigafactory. They:

✅ Excavated a canal on Blount Island, Jacksonville, Fl
✅ Installed the world's largest gantry crane
✅ Submitted a full EIS for sites up and down the Atlantic coast
✅ Got an actual license from the Nuclear Regulatory Commission to manufacture the first 8 reactors(!)
